“A bell cannot tell time, but it can be moved in just such a way as to say twelve o’clock – similarly, a man cannot calculate infinite numbers, but he can be moved in just such a way as to say pi.”
– Daniel Tammet, in Thinking In Numbers: How Math Illuminate Our Lives
22/7 is a close approximation of Pi. It is two decimal places from Pi. Because of this, Pi Approximation Day is observed on July 22. We can all thank Archimedes for this!
